"0 @ZZ whom t may concern:

Be it known that I, JOHN Il. GRAY, a citizen of the United States,residing at Elwood, in the county of Gosper and State of Nebraska, haveinvented a new and useful hub to be used in all kinds of wheels whereinthe hub and spoke enter as a necessary part for .its use andapplication, ot' which the following is aspeciication.

My inventionv relates to improvements in hubs for vehicles and refersespecially to a metallic hub, and the object of my invention is theprovision of a hub which will possess merit in point of simplicity,durability, cheap ness and efficiency and thus prove a practicalimprovement. y

The invention consists of a metallic hub embodying novel features ofconstruction and combination of parts substantially as dis`- closedherein.

In order that the details of construction of my hub and the advantagesarising therefrom will be understood I invite attention to theaccompanying drawings.

Figure l represents a vertical sectional View of my hub. Fig. 2represents a similar view with collar and washer in place. Fig. 8represents an elevation of the hub partly in section. Fig. 4 representsdetail views of the collar or sleeve and Fig. 5 represents detail viewsof the washer.

In the drawings--A designates the outer section of the hub having theouter threads or and the interior threads a', and B designates the innersection having the interior threads b and between the iianges b of thesesections are clamped the spokes l-l.

In the sections A and B is received the sleeve C having the reduced endc provided with exterior threads c and the larger inner end c2 havingthreads c3, the threads on the sleeve engaging those of the clampingsections, and in the sleeve bore is placed the skein D, having theshoulder d, provided with exterior threads d which engage the threads c4of the sleeve and secure the skein in the sleeve and in the skein ts theaxle E, the outer threaded end of which receives the nut F and the dustcap G screws upon the section A.

To secure the spokes more effectively in place I provide the beveledcollar O which surrounds the sleeve and the beveled washer P, which arearranged as shown in Fig. 2 and act as wedges to hold the spokes.

lt will be seen that I provide a hub made entirely of metal and theparts of which fit snugly together and hold the spokes firmly andprovide a simple, durable, cheap and entirely practical hub. i

I claim- 1. A hub consisting of the two clamping sections, the spokes[itting between the flanges thereof, the sleeve fitting in the sections,the collar surrounding the sleeve, the washer adjacent to the sleeve,the spokes resting against the sleeve and collar and the skein in thesleeve. y

2. A` hub consisting of the two clamping sections, the spokes securedbetween the flanges of the sections, the beveled sleeve and washerwedging the spokes the sleeve having the reduced and enlarged endsengaging the sections, and the skein fitting in the sleeve and havingthe threaded shoulder.

3. A hub consisting of the clamping sections, the spokes between thesame, the sleeve fitting in the clamping sections, and the collar andwasher serving as wedges for the spokes,

as described.
